Paper Birch
Betula papyrifera
White Birch, Paperbark Birch, White Paper Birch, Snow Birch
Height: 50-70' (15-21 m).
Diameter: 1-2' (0.3-0.6 m).
Leaves: 2-4" (5-10 cm) long, 1 1/2-2" (4-5 cm) wide. Ovate, long-pointed; coarsely and doubly saw-toothed; usually with 5-9 veins on each side. Dull dark green above, light yellow-green and nearly hairless beneath; turning light yellow in autumn.
Bark: chalky to creamy white; smooth, thin, with long horizontal lines; separating into papery strips to reveal orange inner bark; becoming brown, furrowed, and scaly at base; bronze to purplish in varieties.
Twigs: reddish-brown, slender, mostly hairless.
Flowers: tiny; in early spring. Male yellowish, with 2 stamens, many in long drooping catkins near tip of twigs. Female greenish, in short upright catkins back of tip of same twig.
Cones: 1 1/2-2" (4-5 cm); narrowly cylindrical, brownish, hanging on slender stalk; with many 2-winged nutlets; maturing in autumn.
Culture: Paper birch grows very fast in youth, but remains a tree of moderate proportions. It rarely lives more than 100-150 years, and rarely exceeds 70 ft (21.3 m) in height.
Light: Paper birch does best in full sun to partial or dappled shade.
Moisture: Like other birches, paper birch has a shallow root system and should be watered during dry spells. It is highly susceptible to the bronze birch borer when not watered enough.
Hardiness: USDA Zones 2 - 7. Paper birch is extremely cold hardy. It almost never grows naturally where average July temperatures exceed 70ºF (21ºC). Trees grown in warmer climates often succumb to bronze birch borers.
Propagation: Propagate paper birch from fresh seeds, which are produced in prodigious numbers. Seeds that have been stored may require cold, moist stratification before they will germinate. The tiny seedlings are particularly fragile and must be coddled for their first few years. Paper birches can also be propagated from cuttings.
Usage: Paper birch is usually cultivated for its highly ornamental bark which is especially attractive in winter, framed by its delicate lacy twigs. A small group of paper birches looks great in front of dark green evergreen conifers. American Indians used the tough, light weight bark of paper birch to cover their wigwams and birch bark canoes, as well as to make baskets, water-tight containers and dishes. They also made a tea from the leaves, a sweet syrup from the sap, and used decoctions of the inner bark for various medicinal purposes.
Description: The familiar paper birch is a slender and graceful deciduous tree with white bark that separates along horizontal slits and peels into thin papery layers, exposing an underbark which is pale orangeish brown. The bark has a chalky covering that rubs off easily, and this is one way to distinguish this tree from other birches with white bark. The paper birch usually gets 50-70 ft (15.2-21.3 m) tall, but can get as tall as 100 ft (30.5 m). It has a conical form and a rather sparse, open crown, more so in age. The leaves are ovate to heart-shaped, toothed, 2-3 in (5.1-7.6 cm) long, and dark green, turning yellow to orange in fall. The staminate (pollen-producing or male) flowers are in hanging catkins, 3-4 in (7.6-10.2 cm) long, and the pistillate (female) flowers are in semi-erect conelike clusters about an inch long. The trees bear both kinds of flowers and these appear before the leaves in early spring. Botanists recognize several varieties of paper birch, and a few naturally occurring hybrids with other birches have been identified. Horticulturists have selected a few cultivars, including 'Chickadee' which is described as especially narrow, and 'Snowy' which is supposed to be resistant to the bronze birch borer.
